Description

Technical Field

[0001] The invention relates to a minimally invasive dilation and drainage kit, in particular to a minimally invasive dilation and drainage kit with a coagulation function. Background Art

[0002] The current disposable minimally invasive dilation and drainage kit usually includes a dilator, a sheath, a renal puncture guide wire, a percutaneous renal puncture guide needle and a renal fistula tube, and is suitable for clinical percutaneous renal puncture. The method of use is: positioning under B-ultrasound, puncturing with a renal puncture needle; after urine flows out of the puncture needle, the renal puncture guide wire or zebra guide wire is retained, and the puncture needle is withdrawn; under the guidance of the guide wire, different types of dilation tubes are used to gradually expand the soft tissue channel from the skin puncture point to the lesion area from small to large; after expansion to the predetermined size, the sheath is retained to establish a renal cavity channel.

[0003] In traditional percutaneous renal surgery, when bleeding occurs, the doctor needs to insert an endoscope into the body through the sheath to check the bleeding location. Due to space limitations in the sheath, the sheath cannot pass through the endoscope and coagulation forceps at the same time, so the endoscope needs to be withdrawn from the body and the coagulation forceps are inserted into the body through the sheath. The doctor uses the bleeding location in his memory to blindly stop the bleeding. If there are many bleeding points, the endoscope and coagulation forceps need to repeatedly enter and exit the human body, resulting in inconvenient bleeding and long operation time. Summary of the invention

[0004] In order to solve the problem that the endoscope and coagulation forceps need to be repeatedly inserted into and out of the human body, which causes inconvenience in hemostasis and long operation time, the present invention provides a minimally invasive dilation and drainage kit with coagulation function, and the specific technical solution is as follows: A minimally invasive dilatation drainage kit with coagulation function comprises: a sheath; a hemostatic ring arranged at the end of the sheath; and a wire arranged on the sheath and connected to the hemostatic ring; wherein the wire is used to supply power to the hemostatic ring so that the hemostatic ring causes blood vessels to form scabs by generating heat.

[0005] Preferably, the minimally invasive dilatation drainage kit with coagulation function further comprises: an outer sleeve, which is sleeved on the sheath and provided with a fixing groove for installing the hemostatic ring, and the guide wire is located between the outer sleeve and the sheath.

[0006] Furthermore, the outer cover is an elastic cover.

[0007] Wherein, the outer jacket is made of polyether block polyamide.

[0008] Furthermore, the minimally invasive dilation and drainage kit with coagulation function also includes: a hydrophilic coating, which is arranged on the outer surface of the outer sleeve.

[0009] Preferably, the sheath is made of polytetrafluoroethylene.

[0010] Compared with the prior art, the present invention has the following beneficial effects: A minimally invasive dilatation drainage kit with coagulation function provided by the present invention is provided with a hemostatic ring on the outer surface of the sheath tube. The hemostatic ring generates heat after being powered by a wire. When the temperature of the hemostatic ring rises, the blood vessels can be scabbed, thereby achieving the hemostatic function, making hemostasis simpler and eliminating the need for repeated use of coagulation forceps. The frequency of use of the coagulation forceps is greatly reduced, the operation time is shortened, and the patient's pain is alleviated. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the structure of this application; Figure 2 is a front view of the present application; Figure 3 yes Figure 2 A partial enlarged view of point I in the middle; Figure 4 is an exploded view of this application; Figure 5 yes Figure 4 A partial enlarged view of point II in the middle. DETAILED DESCRIPTION

[0012] The present invention will be further described with reference to the accompanying drawings.

[0013] The sheath 1 in the traditional minimally invasive drainage kit is improved so that the sheath 1 has a coagulation function, which solves the problem of inconvenient hemostasis and long operation time caused by the need for an endoscope and a coagulation forceps to repeatedly enter and exit the human body. During the operation, the hemostasis can be performed more quickly, accurately and conveniently, reducing the pain of the patient.

[0014] like Figures 1 to 5 As shown, a minimally invasive dilatation and drainage kit with coagulation function includes a sheath 1, a hemostatic ring 4 and a wire 6. The end of the sheath 1 is equipped with a hemostatic ring 4, which has a certain resistance. The hemostatic ring 4 can generate heat after being energized. The heated hemostatic ring 4 scalds the blood vessels to form scabs, thereby achieving the hemostatic function without the need for coagulation forceps. The hemostatic ring 4 is also connected to the wire 6, which is connected to an external minimally invasive device. The minimally invasive device controls the heating of the hemostatic ring 4 through the wire 6.

[0015] The hemostatic ring 4 can be made of stainless steel or an electric heating film. The hemostatic ring 4 is fixedly connected to the wire 6 to ensure reliable conduction. Two hemostatic rings 4 are grouped together to form a pair of electrodes. A high-frequency current flows between the two electrodes. The thermal effect of the high-frequency current is used to dehydrate and shrink the blood vessel wall, coagulate the blood in the blood vessel, and integrate the blood vessel and the blood clot, thereby achieving the purpose of effective hemostasis.

[0016] The sheath tube 1 is used as a passage for the instrument to enter and exit. The sheath tube 1 is an existing mature product and will not be described in detail here. The outer surface of the sheath tube 1 is provided with scales. The sheath tube 1 can be made of polytetrafluoroethylene.

[0017] In order to facilitate the hemostasis operation and accurately control the hemostasis position, two hemostatic rings 4 are provided along the axis of the sheath tube 1. The hemostatic rings 4 correspond to the wires 6 one by one, and the wires 6 can be arranged on both sides of the sheath tube 1 so that the two wires 6 do not contact each other to avoid short circuit.

[0018] In order to make the outer edge of the sheath 1 smooth and make it easier for the sheath 1 to enter and exit the human body, the minimally invasive dilatation and drainage kit with coagulation function also includes an outer jacket 2, which is sleeved on the outer surface of the sheath 1. The outer jacket 2 is provided with an annular fixing groove 21, and the hemostatic ring 4 is installed in the fixing groove 21. The wire 6 is located between the outer jacket 2 and the sheath 1. The outer surface of the hemostatic ring 4 can be flush with the outer surface of the outer jacket 2, or slightly lower than the outer surface of the outer jacket 2, so that the outer surface of the outer jacket 2 is smooth, thereby reducing the pain of inserting the sheath 1 into the body and improving comfort.

[0019] In order to further improve the smoothness and comfort of the outer cover 2 when entering and exiting the human body, the outer cover 2 is an elastic cover. The outer cover 2 can be made of polyether block polyamide.

[0020] In order to improve lubricity and make the sheath tube 1 enter and exit the human body more smoothly, the outer surface of the outer cover 2 is also provided with a hydrophilic coating, the main component of which is polyethylene.

[0021] The hydrophilic coating will be activated when it comes into contact with human tissue fluid, greatly increasing the lubricity of the surface of the outer sheath 2, allowing the sheath 1 to smoothly enter and exit the human body.

[0022] A hemostatic ring 4 is provided at the end of the sheath 1, and the coagulation forceps function is integrated into the sheath 1; if bleeding is found during the operation, it is only necessary to insert the endoscope, confirm the bleeding location, and use the hemostatic ring 4 on the sheath 1 to achieve hemostasis; compared with traditional instruments, there is no need to withdraw the endoscope, and the endoscope can maintain an observation state in the body, so that the doctor can find the bleeding location more accurately and stop the bleeding more quickly.

[0023] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the protection scope of the claims of the present invention.
